follow one of two plates respectively termed upper formation plate -orlowerformation plate ;l they willy further produce boX plaits. when theyvare made toV follow alternately the said upper and lower plates. In allcases, by virtue of thecontinuou's form oit the plaiting blades, theplaits or folds will be 0f the same character over all the length Myinvention, which is a division of ,my pending application N @53,705filed August 31', 1925, has foritsobject an improved `plaitingmachineatfording the obtainment of patterns, designs and folds which arereversed in the lengthwise direction of the fold. Said machine ischieflyfcharacterized in that itcomprises a plurality yof ypivotedplaitingLblade elements disposed upon the length of the machine, andthatcertainof` the said elements may be given differentmoveinentsrelatively to the others.V

Various other features of the invention willfbe` setforth inthefollowing description with reference to the appended drawings, given byway of example, and relative to an embodiment of thesaid invention.V

Fig. l is a section of the machine with the plaiting blades in the frontposition, and

F 2 is a like view withy the `plaiting blades .in contact-- with theformation plates.

The upper blade elements 14 are secured to the blade carriers40rotatable upon a shaft or tube 41constituting the upper frame yoft-hemachine.v The lower blade elements 14 are secured in like manner to theblade carriers 42 mounted on ,the shaft or tube 43 constituting thelower frame of the machine. 43, carries at each end two standard plates4 in which the upper frame, that is the tube 41, isadapted ,to rotate.The plates 4 are providedv with journals G which are given a straightreciprocating motion towards and away from the cylinders as usualfor theblade of plaiting machines.

A Ceshaped member 7 is secured to the tube 41 and is supported throughthe mevThe lower frame, that is y.the tuber Divided and Serial No.142,798.

dium of a roller 8 upon a plate 9 which may be raised duringtherearwardstroke away from `the cylinders of the journals 6 and of ythe tubes 41and 43, as usual in Well-known latter is not controlled, and when thesaid lower element is controlled, it will in turn rcause the upperelement to rise. The lower frame or tube .43 is adapted to receive an`oscillating rotation by controlling means not represented and generallyused in the known plaiting machines. l

'The carriers 42, rotatable on. the tube 43,

are each providedwith a pin or stud46 eX- tending and adapted toslidethrough the same; said studis urged outwardly by a spring 47 and whenthe latter is compressed,

the stud may engage in a corresponding aperture 48 vin the tube 43. Whenthe stud is in the position shown in Fig. l, the corre- ,sponding bladeelement will .be loose on the tube.

The corresponding upper blade carwhicfh is urged intoits lower position.the spring 20, will oblige the lower blade rier 40,

,b Qelement to assume its lower position, thusr providing for theformation 'of an` underlapping plait.

The insertion of the studs .46.into the tube 43, for connecting togetherthe Asaid tube and ,the blade carrier v42,l is controlled by camelements or bosses 37 disposed incircularrows upon a rotary 'drum 36 towhich a continuous or intermittent motion maybe imparted;

each row ofcam elements 'corresponds to one pm or stud 46, and the camelements of one row may. control yt-he inward motion of theVCorresponding pin 46 throughthe medium of a rocking arm 32 mountedloose on a com-mon shaft 33 and providedrwith aroller 34 situated in thesame plane as lthe cam elements 37. Each ofthe lattermay be removablysecuredy upon the drum for instance by means of a shank adapted toengage a hole provided in the periphery of the drum. The drum may begiven an intermittent rotary motion, so that itis rotated through halfthe angular space between two consecutive holes of one row at the end ofthe forward and rearward strokes of the lower frame, each hole, or thecam element engaged therein, being in line with the roller 34 of thecorresponding arm 32 during the forward stroke of said lower frame.

Then a boss 37 engages the roller 34 of one lever 32, the latter will beraised, thus causing the stud 46 to enter the recess 4S in the tube 43.The corresponding blade element 42 is thus connected bv the stud withthe tube 43 and will hence follow the movementsk of the latter and willproduce either overlapping plaits or under-lapping plaits. If there areno bosses engaging the roller 34, the correspondingr blade element willproduce an underlapping plait. l

I am thus enabled to modify the nature of the folds made by each bladeelement during the course of the work, without stopping the machine, byinserting or withdrawingr the corresponding boss 37. i

Fig. Q shows blade carriers 4Q. which are connected by their studs withthe tube 43 and thus are in a position corresponding to the l formationof overlapping plaits, and other blade carriers 42h, which arey loose onthe tube 43 and are in a position corresponding to the formation ofunderlapping plaits.

It will be observed also that upon the whole length ot the tube 41 is agroove 44 in which engage stop screws 45 respectively carried by theYblade carriers 40. When the C device rotates the tube 41, the latterwill drive at a certain moment, the screws 45 of all the blade elements,so that the latter will be opened. The said groove 44 has sufticientwidth so that when the C device is inoperative, the blade elements mayassume the upper or the lower position.

Obviously, I may substitute for the drum with removable bosses, a band,for instance of cardboard, which is either perforated or is providedwith removable bosses, and which is movable below the control levers,thus serving the same purpose as the above described drum.

Having now described my invention,` wh at I claim as new and desire tosecure by Letters Patent is:

kl. In a plaiting machine the combination with two pressing drums andwith the upper and the lower longitudinal frames, of two sets ofplaiting blade elements rotatably mount-edy on said frames and meanswhereby the blade elements of said lower frame are intermittentlysecured and unsecured to their shaft during the forward stroke of saidlower frame for the purpose set forth.

2. In a plaiting machine the combination with two pressing drums andwith the upper and the lower longitudinal frames, of two sets ofplaiting blade elements rotatably mounted on said frames, springcontrolled studs respectively adapted to secure to the lower frame theplaiting blade elements mounted on said lower frame, and normally out ofengagement with said frame, and means whereby said studs are caused toengage said frame, and thereby secure said latter plaiting bladeelements to the same during the forward stroke of said lower frame forthe purpose set forth.

3. In a plaiting machine, the combination with two pressing drums andwith the upper and the lower longitudinal frames, of two sets ofplaiting blade elements rotatably mountedy on said frames, springcontrolled studs respectively adapted to secure to the lower frame theplaiting blade elements mounted on said lower frame, and normally out ofengagement with said frame. a support adapted to be moved in front ofsaid studs and rows of cam 'elements respectively corres onding to saidi" studs and mounted on sai support according to a predetermineddisposition and whereby said studs are caused to engage saidcorresponding frame and thereby secure said latter plaiting bladeelements to the same, during the forward stroke of said lower frame.

4. In a plaiting machine the combination with two pressing drums andwith the upy per and the lower longitudinal frames, of two sets ofplaiting blade elements rotatably mounted on said frames, a longitudinalgroove in the periphery of the upper frame, studs respectively providedon the plaiting blade elements mounted onv said upper frame and engagingsaid groove, yielding means whereby each of the plaiting blade elementsmounted on said upper frame are constantly urged towards the oppositeplaiting blade elements mounted on the lower trame, and means wherebyeach of said latter plaiting blade elements may be brought at will intoits lower position and into its upper position for the purpose setforth.

5. In the combination as claimed in claim 4, the further featureresiding in that the width of said groove is such that when said upperframe is stationary the plaiting blade elements carried thereby mayassume their upper or their lower position.

In testimony whereof I have signed my name to this specification.
